Berkeley CS 61B Data Structures(in Java) Project1 加分+讨论帖

**终于在de了无数bug之后把partI做出来了。。。。哎，过程太艰辛。。。先上个结果吧。TAT

netbeans不知道为什么输入命令后总是找不到图片java.lang.IllegalArgumentException: "flower.tiff": File not found.这个靠我自己真是搞不定了。。。都木有图能看到感觉成就感全部都消失了，好伤心。。。。。。。。
楼主你直接在terminal里执行么？图片你是存在哪里啊？

做的06年的Project1，发现写完part 1代码就可以成功运行了，并且给出的代码不好测试part2-4写的对不对，不知道楼主做了part2-4没有？我part2-4写好了，但不知道对不对

终于把project1做完了！！part3和part4真是debug到死啊。。
用这个RLE压缩算法可以把164kb的tiff图片文件压缩到68kb，还是很牛逼的！
贴上图和作业~求学分T.T

楼主你太耐心了~61b看完了没？我就因为这个给自己一个借口。。。原地踏步了好久=.=天天自责

你好，xiaolin_super。我现在也正在考虑part i 的边界处理问题。我看了instruction, 感觉做sobelDection的时候的边界时，只需要相当于边界朝上下左右扩展就行了，关于energy的问题，也不涉及到边界了啊。因为算边界energy的话，我们已经得到了边界的各个分量的梯度了。不知道我分析得对不对？求指点。

花了一上午写啊，调啊，把part I部分弄出来了。

查了好久右下角那个点的sobel还是不对...
